Datasheet
ISL22511
Low Noise, Low Power, 32 Taps, Up/Down, Single Push-Button Controlled Potentiometer (XDCP™)
The ISL22511 is a three-terminal digitally-controlled
potentiometer (XDCP) implemented by a resistor
array composed of 31 resistive elements and a wiper
switching network. The ISL22511 features a
push-button control, a Shutdown mode, and an
industry-leading UTQFN package.
The push-button control has individual PU and PD
inputs for adjusting the wiper. To eliminate
redundancy, the wiper position automatically
increments or decrements if one of these inputs is
held longer than one second.
Forcing both PU and PD low for more than two
seconds activates shutdown mode. Shutdown mode
disconnects the top of the resistor chain and moves
the wiper to the lowest position to minimize power
consumption.
The three terminals accessing the resistor chain
naturally configure the ISL22511 as a voltage divider.
A rheostat is easily formed by floating an end terminal
or connecting it to the wiper.

Notes:
1. See TB347 for details about reel specifications.
2. These Pb-free plastic packaged products employ special Pb-free material sets; molding compounds/die attach materials and NiPdAu-Ag
plate - e4 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J-STD-020.
